In this video, near 1/2, a dc-dc converter is used to match a panel to a load.

parts 1 and 2 are worth watching!
Thanks. I have not hoisted in how matching the load to the panel's MPPT output will get you max amps, but it might sink in eventually.
Also he did not seem to take into account panel temperature for its output.
I could never figure out this past summer if the panel was low on watts from high temperature or if it is a "demand thing" once the batts are near charged when the amps are not up there and the Eco-W shows low watts too.
If you increase the load above battery demand, the amps go up and the Eco-W watt-meter shows more watts, but it never gets near panel rating 230w.
There are losses even at the best of times (best about 210w) but it is such a chicken and egg thing, I can't ever understand what is really happening. Most of the summer, best was about 180w and best amps about 13.5, but earlier in the Spring's cooler temps, watts were nearer 200 and amps were 15.5.
Anyway, just increasing the load does not by itself get you to the panel's specs for wattage, it is still less than that when the panel is hot.
